以前报道,茶褐蓑蛾Mahasena Colona Sonan主要分布于淮河以南部分茶区。笔者于1991年对其雌蛹重与产卵量的关系进行研究,现简述于后。材料和方法 1.老熟雌性幼虫的获得:茶褐蓑蛾雌蛹历期11～15天,平均12.7天;而雄蛹历期19～32天,平均22.7天。一般是雄幼虫在化蛹后10天左右,雌性幼虫才化蛹,且近老熟雄幼虫护囊的尾部附有雄幼虫的蜕皮。所以在雄幼虫开始化蛹后,到田间采集尾部无蜕皮的虫囊,幼虫大多皆为雌性,后移入室内水培茶枝饲养。
It was previously reported that the Mahasena Colona Sonan is mainly distributed in the tea plantations south of the Huaihe River. In 1991, the author studied the relationship between the female pupal weight and the fecundity, which is summarized in the following. MATERIALS AND METHODS 1. Obtaining of mature female larvae: The female pupae of Chamaeleuria sasakii had a duration of 11-15 days with an average of 12.7 days; while the male pupae lasted 19 to 32 days with an average of 22.7 days. Male larvae are generally about 10 days after the pupation, female larvae were pupation, and the larvae near the end of mature larvae attached to the male larvae molting. So after the male larva began to pupate, to the field to collect tailless molting worm larvae, most of the larvae are female, after moving into the indoor hydroponic tea branch breeding.
